WD1500AD Raptor faster than RAID 0

I bet some of you already knew this, but its news to me.

the Raptor 150 is faster than two 7200rpm drives in RAID 0 configuration.

read all about it here...

http://www17.tomshardware.com/2006/0...formance_lead/

The new Raptor reaches a maximum transfer performance rate of more than 80 MB/s when the drive is empty; this is when the drive usually uses the outer area of the rotating platters where the absolute rotation speed is highest. The more capacity you utilize, the more the transfer rate is going to decrease; this is normal for all drives. The minimum transfer speed, however, is even more impressive than the maximum number. The Raptor-X does not fall below 55 MB/s, which some 7,200 RPM drives cannot even provide as a maximum.

It's not faster than my IRAM drive, so I give the "alright." I'll probably pick another one up for R0 configuration...

4GB on the IRAM, 3200 sticks. It's fast, I'm navigating Windows in 9 seconds.


That's me!

I'm navigating Windows in about 18 seconds now with a single 74gb Raptor II. Good enough for me.

hmm, tempting. I have way more hard disk than I actually need, but it's nice to have a fast hard disk. It's definitely the bottleneck on my system.

Raid 0 configurations are achieved using a Raid controller. They can be found on your motherboard if available or stand alone PCI controller. It basically writes half the data on one drive, other half on other, zeros on one drive, ones on other. The OS will see the two drives as one. In your situation your total size would be 320gb.

When I mentioned "navigating speed" on the other post I meant from the time I push my ON button to the time Windows is fully responsive and done loading startup services, drivers and applications. So it's not really a formal speed or benchmark...

Not loud to me, it has to compete with 3 case fans. WD, Seagate, I've never noticed a loudness difference...

theres a difference between mine thats as clear as night and day, like just to check things out, i unplugged all my wd hardrivers and just ran my seagate, my computer was really quiet, then i just plugged in 1 WD drive, loud as hell. i thought hey maybe its cause this drive is like 3 years old, so then i plugged in the newest WD i got like less than a year ago.. still loud as hell..

.. well its not really the ticking or whatever noise it makes while its accessing and stuff that i can hear, its just the loud ass whining noise thats coming from it i guess as the platters just spin.. and it cant be my case fans cause i only have 1, and thats for my water cooling system.

It will be on your BIOS. Keep in mind though, there is two types of RAID: software and hardware.

Software, like Intel's ICH5R chipset, must use a driver to take full enhancements of RAID (example of this is Intel's Matrix RAID Configurer).

Hardware, like 3Ware (who btw, is very very good), are out-of-the-box controllers that require no setup and no OS-based driver support. Of course, it is much much faster. Plus it is hot swappable.

If anything run RAID 0+1 for reliability and speed. If you don't care about your data and just want balls out speed, do RAID 0.
